BT136 is a type of electronic component, which is a triac. The thyristor is also the abbreviation of the thyristor rectifier element. It is a high-power semiconductor device with a four-layer structure with three PN junctions, which is generally formed by reversely connecting two thyristors. 

There are many different ways to use a TRIAC, since the device is bi-directional the TRIAC gate can be triggered with either positive voltage or negative voltage. So this allows the TIRAC to be operated in four different modes. You can read this article if you want to know more about switching modes.


  • Because of the bidirectional control of alternating current, these components are used as different controllers for AC, fan, heater, static switch with three positions, triggering devices for silicon-controlled rectifiers, light dimmers, etc.
  • AC Light dimmers
  • Strode lights
  • AC motor speed control
  • Noise coupling circuits
  • Controlling AC loads using MCU/MPU
  • Power control of AC or DC
